Hmmm. I've always thought the exact opposite to be true. The scientific method seeks not only contradictory evidence to disprove a hypothesis, but also corroborating evidence to support one. Existence leaves behind evidence. In fact, that may be a pretty good working definition of existence.

If I remember correctly, there was a song on the radio about Big Foot. I heard it while vacationing out West, and the song was pretty popular localy. I never heard it in Chicago. It went something like this, but if I mess it up, please excuse me. I am relating something I heard on a tiny transistor radio in the mid 70s.
